Title: Mounting method for optical waveguide module
Inventor: NAKAJIMA KAICHIRO
IPC: G02B6/122
Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a mounting method in which degradation due to inserting loss is suppressed when a thermally contracting tube is mounted into an optical waveguide module where at least one optical fiber is connected and fixed to the both sides of an optical waveguide chip such that optical axes of optical fiber blocks alignedly fixed on a substrate are coincident. SOLUTION: When a thermally contracting tube is mounted to improve long term reliability into an optical waveguide module where at least more than one optical fiber is connected and fixed to the both sides of an optical wave guide chip such that optical axis of optical fiber blocks aligneadly fixed on a substrate are coincident, by decreasing the internal temperature of the thermally contracting tube to at least 20 deg.C lower temperature than glass transition temperature of adhesive agent which is used for connection to glass, mounting of the tube does not degrade the inserting loss. Providing at least 300 deg.C of heat within five second during the mounting suppresses degradation of inserting loss due to the tube mounting.

Title: Desulfurization method of molten iron alloy
Inventor: MIYAJI YOSHINOSUKE
IPC: C21C7/064
Filed: 1979-02-08
Abstract: PURPOSE: To effectively desulfurize molten iron alloy without causing high-temperature hot air blowing-out by forming alkali carbonate to the spherical shape of the specific size and bulk density and adding the same to the molten iron alloy through air current blowing at the time of desulfurizing the molten iron alloy with alkali carbonate.  
     CONSTITUTION: In order to desulfurize molten iron alloy, its molten metal is put in a torpede car and is desulfurized with alkali carbonate such as sodium carbonate. Here, the sodium carbonate of the spherical form of 1.0W4.0mm in diameter and 1.1 or more in bulk density is used. This spherical sodium carbonate is blown into the bath by gas such as N 2  or Ar at a speed 100W300m/sec. As in the case of using powder sodium carbonate, the phenomenon that the hot air of high temperature blows out from the molten iron alloy take-out port in the upper part of the torpede car does not occur and the desulfurization may be accomplished by a small amount of sodium carbonate with good efficiency.

Title: Production of compound semiconductor single crystal
Inventor: SHOJI TAKASHI
IPC: C30B17/00
Filed: 1994-01-12
Abstract: PURPOSE:To readily and efficiently produce a relatively long compound semiconductor single crystal by specifying the ratio of the shortest distance to the longest distance between the rotational center of a seed crystal and the inside wall of a crucible in the liquid-sealed chyloporous method. CONSTITUTION:A crucible 3 is put in a high-pressure tank 1 and raw materials 6 and a liquid sealing agent 7 are fused in the crucible 3 in an inert atmosphere. A seed crystal 9 is then dipped in the fused raw materials 6 and the heating temperature is controlled while rotating the crucible 3 and the seed crystal 9 respectively to grow a compound semiconductor single crystal having a prescribed diameter. In this case, the ratio of the shortest distance/the longest distance between the rotational center of the seed crystal 9 and the inside wall of the crucible 3 in the same horizontal plane is controlled to 0.75 to 0.99, e.g. by making the shape of the horizontal cross-section of the crucible 3 elliptic. A gap is left between the single crystal and the crucible 3 thereby and, therefore, the resistance to slip between the single crystal and the crucible 3 can be reduced. Consequently, the convection of the fused raw materials 6 can be readily controlled and the ratio of single crystal formation can be improved.
